Build with Python

A GitHub repository by user rohitg00 called 'ai-engineering-from-scratch' is trending, described with the tagline 'Learn it. Build it. Ship it for others.' It is a Python-based educational resource aimed at people who want to learn AI engineering from first principles and move toward shipping real applications. The repository has collected hundreds of stars today. The snippets do not reveal exactly what sparked the surge in attention, beyond apparent interest in self-taught AI engineering material.

Trigger.dev has introduced Plimsoll, an open-source Python sandbox that lets AI agents safely execute code while analysing data. Agents often need to run calculations, inspect files, or test snippets, and the sandbox provides an isolated environment for that. Developers in the open-source community are sharing the tool as a practical addition to agent-building workflows.

Developer Pyxel announced that his MIT-licensed retro game engine for Python, in development since 2018, has passed 18,000 stars on GitHub. The free engine includes built-in pixel art and sound editors, letting creators build retro-style games entirely in Python. The milestone announcement is drawing attention from hobbyist game developers and Python programmers discussing the tool's all-in-one approach.

Developer kitao has released Pyxel, an open-source retro game engine for Python that includes built-in pixel art and sound editors, letting creators build games in a single environment. The project, hosted on GitHub, is drawing attention from developers interested in simple tools for making retro-style games, and discussion is focused on how it compares to other game-making frameworks.

A new beginner-level Python course called Build with Python has been launched, starting with a lesson on drawing with code. The course is aimed at people new to programming and uses visual, drawing-based exercises as a way to learn. It is being shared and discussed among developers interested in teaching tools for beginners.

A new open-source course on building production-ready agentic retrieval-augmented generation systems is gaining attention among developers. Released by jamwithai and written in Python, the repository walks through deploying RAG pipelines with autonomous agents in real-world settings. Interest is growing as teams move such systems from prototypes into production.

TileLang, a domain-specific language for writing high-performance kernels for GPUs, CPUs and other accelerators, is drawing attention among developers. Written in Python, it aims to simplify kernel development that would otherwise require low-level tuning. Interest is focused on its potential to make AI and scientific computing workloads faster to build and easier to optimize across hardware platforms.

NVIDIA has released IsaacTeleop, a new framework that converts XR hand tracking and motion controller input into commands for both simulated and real robots. The pure Python retargeting engine allows developers to build robot control systems using NumPy, lowering the barrier for prototyping teleoperation and robot training workflows. Robotics developers are welcoming the open approach, seeing it as a practical tool for controlling robots with consumer VR hardware.

Hacktoberfest 2026 is underway, and computer science students are announcing their participation by making their first open-source contributions. One student shared that they have been learning Git, GitHub, web development, Python and AI, and wanted to finally experience contributing to open-source projects. The annual October event, run by DigitalOcean, encourages developers worldwide to submit pull requests to open repositories and has become a popular entry point for beginners building portfolios.

The Python community across Africa will meet in Kampala, Uganda, from October 7 to 11 for PyCon Africa 2026, a conference bringing developers together to learn, build and share ideas. Organisers are calling for donations, sponsors and partners to fund the event, saying every contribution helps make the gathering possible.
